Problems solved by technology
[0003] Existing plasma treatment equipment is mainly based on rotary spray guns, DC spray guns and wide-width plasma machines. The length of plasma flames produced by conventional DC spray guns is generally 0-20mm. The short length results in a treatment range that is not large enough to meet the needs of large-sized metals. The processing requirements of the products, and the instantaneous temperature is low, and the effect is not ideal when processing metal products. Therefore, a plasma nozzle that can make the DC spray gun produce a longer flame is needed to increase the processing range of the DC spray gun and improve the DC spray gun. The instantaneous temperature generated by the spray gun is conducive to high-temperature treatment of metal products

The invention discloses a plasma nozzle, which comprises a nozzle body, wherein a first spraying opening and a second spraying opening are formed in the two opposite ends of the nozzle body correspondingly, the first spraying opening and the second spraying opening are circular, the diameter of the first spraying opening is larger than that of the second spraying opening, a spraying channel communicating with the first spraying opening and the second spraying opening is formed in the nozzle body, the inner circumferential wall of the spraying channel is conical, a plurality of third spraying openings are further formed in the end, provided with the second spraying openings, of the nozzle body, the third spraying openings are in a linear shape and are arranged in a radial shape, and the third spraying openings communicate with the spraying channel. According to the plasma nozzle provided by the invention, the plasma flame with the length of 30-40mm is generated, and the instantaneous temperature of the plasma flame can reach more than 200 DEG C so as to reach the temperature required for treating the metal products, so that the metal products with various sizes can be treated, and the universality is high.
Description
technical field [0001] The invention relates to the technical field of plasma processing equipment, in particular to a plasma nozzle. Background technique [0002] Plasma is an ionized gaseous substance composed of positive and negative ions produced by ionized atoms and atomic groups after part of their electrons have been deprived. Plasma is a good conductor. It can be captured, moved and Accelerated plasma, the development of plasma physics provides new technologies and processes for the further development of materials, energy, information, environmental space, space physics, geophysics and other sciences, so plasma is widely used, including digital industry, Electronics industry, automobile industry and printing and packaging industry, etc. [0003] Existing plasma treatment equipment mainly consists of rotary spray guns, DC spray guns and wide-width plasma machines. The length of the plasma flame produced by conventional DC spray guns is generally 0-20 mm, and the sho...
